Van purchase problem on SA

[cookhead]

I have a problem with a van purchase for work and I need some advice please.

I bought a new van in Nov 15, paid in full for it, no lease or HP etc. I should have accounted for it on my tax return for the year 15/16 but (this will amaze you) I just completely forgot to do so - I think for some reason I mixed up the dates in my head or something, anyway, it never went on my return for that year.

How would I include it now in my 16/17 return being the purchase receipt is dated Nov 15? TIA.

Having in effect disclaimed the 100% Annual Investment Allowance in 2015/16, you can claim on your amended tax return 2016/17 and in the following tax years the 18% Writing Down Allowance on reducing basis.

When you sell or scrap the van, there will be a balancing charge or a balancing allowance.
